Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and taking the analysis of monkey eye movements as an example:

[0028] The digital video eye movement analyzer is composed of a video input device (1), a frame grabber (2), a microprocessor (3) and a display screen (4). The video input device (1) can be a video camera with a standard rate or a non-standard rate, or a standard device that can obtain images. Install the video input device (1) on the front straight arm of a clip ring similar to a headset, wear it on the head of the monkey to be tested, and aim it at the monkey’s eyes. The clip ring will not damage the monkey’s head or Any part of the body. The video input device (1) transmits the analog or digital image of the monkey eye to the frame grabber (2) through the cable or data bus, and the frame grabber transmits the digital image to the microprocessor (3) through the data bus. The monkey eye image is After...

Abstract

The invention relates to a digital video eye movement analyzer, which belongs to the technical product in the field of machine vision. The digital video eye movement analyzer is composed of a video input device (1), an image acquisition card (2), a microprocessor (3) and a display screen (4). Machine vision technology is used to identify eye movement trajectories, and the steps to identify eye movement trajectories are eye movement series image acquisition, digital image processing and analysis, storage and display. The analyzer has the advantages of non-contact, non-destructive, digital, and adjustable sampling period. It can not only automatically track eye pupil movement online in real time to obtain eye movement trajectories, but also display eye movement true color images. It can be widely used in biological, animal, medical, public security and other industries to analyze human or animal psychological and behavioral activities, and can also be used for clinical diagnosis and medical treatment.

Description

Technical field: [0001] The invention relates to a digital video eye movement analyzer, which belongs to the technical field of machine vision. Background technique: [0002] The technology of using machine vision technology to identify identities based on the human body's own physiological and behavioral characteristics has aroused widespread concern in the international academic and business circles. Human physiological characteristics mainly include fingerprints, facial images, iris, etc., and human behavior characteristics mainly include handwriting, voice, and so on. The current research on the recognition of human eye pupil and iris image is mainly aimed at human identity authentication [1]. However, it is rarely reported to recognize the mental activity of people or animals according to their physiological characteristics (pupil and iris). Citation file [1]: J.G. Daugman. United States Patents No. 5,291,560 (issued March 1994). Biomedical Personal Identification System Bas...
